1/4 cup fresh chives, chopped, plus more for adding after the quiche is baked.
Salt and pepper
1 frozen pie crust thawed enough to roll out.
Instructions
Preheat oven to 350 degrees.
Peel the onions and slice them very thin using a mandolin or a sharp knife. Sauté in a pan with a little olive oil, just until softened, and when they begin to caramelize.
Prepare the pie crust using store-bought or homemade. For mini quiches in regular-sized muffin tins, I cut 3.5″ rounds using a biscuit cutter and placed them in a greased muffin tin.
Blind bake the crust for about 8-9 minutes.
Meanwhile, whisk the eggs and cream. Then add the chives, mustard, and parmesan cheese. Add salt and pepper.
Then layer in the sautéed onions and a little of the Gruyère cheese on the bottom of each quiche cup.
Crumble the goat cheese on top, and pour the egg mixture into each cup.
Bake for about 2o to 25 minutes until the quiche has puffed, browned a little, and set in the center. If the crusts look a little too brown at the end of baking, cover loosely with aluminum foil until done.
